    Or is progressive scan strictly component only?

    DVI spec is for minimum of 480P....

    DVI in digital form is RGB colourspace
    DVI-I cables and sockets can also carry RGB signals.

    Gordon thank you for your reply but that doesnt make any sense to me at all :-(
    What is this 480p? I know it is to do with resolution but thats about it. And what is the RGB colourspace?

    You ask can a progressive scan signal be sent through a DVI cable.....

    NTSC is 480i (480 HORIZONTAL lines of resolution sent as 240 lines per 60th of a second)
    PAL is 576i (576Horizontal lines of resolution sent as 288 lines per 50th of a second)

    The i stands for INTERLACED.
    If it were 480P or 576P then the P would stand for progressive. Then we would have 480 horizontal lines or 576 lines per 60th/50th of a second.
    Progressive signals can be sent as RGB or YPrPb...there are many forms of RGB signals. Both of these signals can be either digital or analogue. DVI sockets if they are DVI-I can handle both analogue and digital as long as they are RGB. If they are DVI-D then only digital RGB.

    I think there is so much to the answer of your question that you need to read and learn more to understand it...so to get you an answer I think will be of more help try this....

    What do you want to send down your DVI cable? What is your source and display?

    thanks again gordon. I will be hoping to upgrade my dvd player soon as at the moment I am just using my PC. Now my plasma came with the scart video board and not the component board which I think retails over £100 if i want to use component. So I am trying to decide what DVD player am I going to use for my plasma? two options
    1. Use the DVI output of a new player such as a denon one and not have to upgrade the video board. or
    2. Get a dvd player that uses component output with progressive scan and fork out for the component video board.

    I just dont know which one wil give the best picture which is why I was asking can you use the DVI route to get progressive scan because if so that kills both birds with one stone. I get progressive scan and dont have to buy a component video board for the plasma. Im assuming it will be the DVI output from a player that gives best quality
